Samples of water will be taken at various points and will be flown back to the USS Rendova for analysis. Additional water surveys will be made on M + 1 day and on following days as required, Distant Atolls: Water samples will be taken from several! distant atolls and islands. The passage of the radioactive cloud will determine the location and the time of the samples to be taken. Transportation will be by Navy PBM. nen aR ay te K.4 RECOVERY PLAN Tables K.1 and K.2 list the projects, means of transportation, and islands to be visited. Table K.1 gives high-priority projects, essential to the success of the operation, which must be recovered as early ag the radiological situation permits, Table K.2 lists all other projects. The time of recovery will depend on the radiological conditions on the islands to be visited and on the availability of helicopters for transportation. In cases where the recovery teams of different projects are composed of the same personnel or where different projects must visit the same isiands, those projects are listed together. The recovery program is based on the assumption that all recovery will be from the USS Rendova, When recovery is to be made by boat, helicopter transportation will be used to Elmer, where the boat will be picked up. The helicopter will then return to the USS Rendova for use by other recovery teams, Radiological surveys will be made of islands to be visited before any recovery missions are scheduled for those isiards, COMMUNICATIONS K,5.2 General The principal communications requirementin the execution of the above plan is that of relaying radiological information from the monitors to RIC. Since the utilization of monitors will be for the most part prearranged, messages pertaining to the employmentof these monitors will constitute only a small portion of the total volume of traffic. The design of this communication plan is thus directed toward a rapid transmission of information from the individual monitor to RIC, with only secondary consideration beiag given to communication between monitors, From M until ME day RIC will be aboard the USS Rendova, and all messages from monitors will be directed there. On ME day both the RIC on the USS Rendova and the newly opened RIC in Building 57, Elmer, will be in operation until full control is assumed by the latter. At this time the Net Control Station on Elmer will notify all member stations of this change and will also report to the TG 132.1 commandnet (J-114) from the new location. K.5.2 Provisions for Monitor-to-RIC Communication ‘General: Prearranged codes by which radiation intensities and location may be reported will be provided each monitor. These codes will be submitted to CTG 132.1 and CJTF 132 for approval in accordance with Operations Plan 1-52, Prior to ME day all communications will be via radio; after ME day landline telephone will be available to certain upper islands as an alternate means of communication. Specific Missions: Aerial-survey monitors will report via helicopter radio to the Commu- nications Center aboard the USS Rendova for delivery to RIC from M to ME day and, thereafter, direct to the Elmer Air Operations Office for delivery to RIC in Building 57, Elmer, oT a ween yer cr At RGoe2 eRREPAY Oe PRR Seerspenssw eno oe tee (ter K.5
